Abstract
A tire noise reduction device includes a noise absorbing member formed of a porous material, a band member formed of a thermoplastic resin, the band member being formed in an annular shape in a tire circumferential direction for mounting the noise absorbing member on a tire inner surface; a bonding member bent into a concave cross-sectional shape, a band bonding section at a key point where the noise absorbing member, the band member, and the bonding member are bonded by interposing the noise absorbing member between the bonding member and the band member. A band width (WB) (mm) of the band member and length (WY) (mm) of the band bonding section in a band width direction satisfy the following Formula (a) and a yield strength of the band section at the band bonding position in an 80° C. environment is 320 N or greater 0.01<WY/WB<0.75 (a).
